I'm not particularly enthralled with the value of eTorque capabilities, but problems with this system seem to have affected early builds. Haven't heard of an issue from anyone in a while now. As far as waiting a long time for parts, supply chain issues run across the board and most certainly are not unique to Ram.
As an example, I have someone in the family that's been waiting five weeks for lifters and a cam for their 2022 Silverado.
